JAMES J. WHITE, OF BOULDER, MONTANA.

BOTTLE-STOPPER.

To all whom it may concern:

Be it known that 1, JAMES J. WHITE, a citizen of the United States, residing at Boulder, in the county of Jefferson, State of Montana, have invented certain new and useful Improvements in Bottle Stoppers; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to bottle stoppers, and more particularly to that class of devices of this nature in which the neck of the bottle must be broken before its contents can be emptied. A disadvantage common to bottles of this nature is that the weakened portion of the neck is below the usual secondary or guard stopper and hence the neck, in such bottles may be broken, the contents replaced by a substitute and the severed portion of the neck united to the bottle in the original position by means of heat.

The primary. object of the present invention is therefore to provide a bottle having an annularly grooved neck, the said groove serving to weaken the neck sufficiently to enable it to be broken and as a seat for the ends of a spring wire which is carried by the guard stopper of the bottle, the said ends of the spring wire being adapted to spring apart when the neck is fractured and prevent rejoining of the parts thereof.

In the accompanying drawings :-Figure l is a vertical sectional view through the upper portion of a bottle showing the invention in position in the neck thereof. Fig. 2 is an elevation of the stopper. Fig. 3 is atransverse section through the stopper. Fig. 4 is a sectional view showing the position which the spring arms assume when the neck of the bottle is broken.

Referring to the drawing more specifically, the numeral 5 denotes the neck of a bottle of any desired construction and 6 an annular groove formed in the neck adjacent the lower end thereof, the groove being of such depth as to insure easy fracture of the neck. Located in the neck 5 directly below the groove 6 is a stopper 7 of cork or rubber which serves the dual purpose of preventing spilling of the liquid when the neck is broken and to protect the liquid from any small particles of glass incident to the fracture of the neck.

Disposed in the neck 5 above the stopper 7 Specification of Letters Patent.

Application filed April 18, 1906.

Patented. June 30, 1908.

Serial No. 312A06.

and with its lower end slightly below the plane occupied by the groove 6 is a guard stopper 8 preferably of glass. Formed at diametrically opposite points in the periphery of the stopper 8 are grooves 9 which extend longitudmally of the stopper and terminate short of the upper and lower ends thereof. An opening 10 which opens at each end into the corresponding grooves is formed clined as at 14 for the reception of the bent lower end of its respective arm.

From the foregoing it will be seen that when the guard stopper is inserted in the bottle neck, the arms will spring outwardly for engagement for their bent ends in the groove 6 and that when the neck is fractured the said bent ends will engage the under edge of the separated portion of the neck and thus prevent the same from being fused. to the remainder. of the neck.

WVhat is claimed, is

The combination with a bottle having a grooved neck, of a stopper provided in opposite sides with grooves terminating short of the upper and lower ends thereof, the inner walls of the grooves being inclined with respect to the inner wall of the neck of the bottle, there being an opening formed through the stopper and communicating with the grooves at their upper ends, and a resilient wire member having a connecting portion seated in the opening and spring arms seated in the grooves and having their lower ends bent to extend into the groove in the neck of the bottle, the said bent portions being of greater length than the thickness of the wall of the neck of the bottle whereby upon fracturing of the neck they may engage beneath the fractured end of the said neck.

In testimony whereof, I afliX my signature, in presence of two witnesses.
